Most asked question about the heater heating modes:

Q: I have set the temp (78F) within 1F higher than the curent water temp (77.2F), but the heater never work on low heat feature, that’s why?

A: Please note that at the first heating stage, low heat feature will not work, the current water temp is 77.2F, you set temp to 78F, the heater will work like this:

1. First stage: heater will work at?MAX heating mode?to heat water up to 78F quickly, low heat feature will not work at this stage.

2. Second stage: water temp reaches the set temp 78F, heater stops heating, water temp will keep at 78F for a period of time.

3 Third satge: water temp begins to drop off, when it drops to 77.5F -77.1F, the heat will starts to work in?ECO heating mode,?the low heat feature works, but if the water temp suddently drops more than 1F lower than the set temp, the heater will work in?MAX heating mode.
